Abstract EN

The experiment was conducted in the lathhouse of Horticulture Department College of Agriculture / University of Kufa in fall season 2014 - 2015 to study the effect of spraying organic fertilizers Optimus Plus and bacteria Azotobacter on the growth and flowers of Mathiola incana L.

The experiment carried out using randomized complete blocked design (RCBD) with three replicates and two factors.

The first factor used three concentrations of organic fertilizer Optimus Plus which ( 0,1.5,3) ml.L-1 and the second three concentrations of bacteria Azotobacter chroococcum is (0, 25.50) ml.L-1 and the interaction between them in the indicators studied.

Treatments mean compared by test averages less significant difference LSD and at the level of probability of 0.05.

The results showed that spraying Organic fertilizers at the concentration 3 ml.L-1 with bacteria Azotobacter at concentration of 50 ml.L-1 the number of colonies 6 × 10-7 colony formation unit / ml was significantly increased from the shoot , root and flowers growth indicators as increased plant height, number of leaves , dry weight of shoots , leaves content of total chlorophyll, total carbohydrates, total soluble length of longer root dry weight of roots , flowering date, the number of inflorescences, number of florets, diameter of rosette and inflorescence holder was given .

The flowering growth indicators reached 139.00 day, 10.67inflorescence.plant -1, 12.67 flower.plant -1, 2.87 m and 8.03 m compared to the contol treatment when reached 154.00day,5.67 inflorescence.plant-1, 5.33 flower.plant-1, 1.80 cm and 4.63 cm respectively.
